Aromatase blocker effectively promotes testosterone, which improves muscle performance and protein synthesis. Considerable strength in Bangkok rooster is the outcome of testosterone activity. Clamshell contains aromatase substances, while fishbone possesses a high amount protein. This research aimed to evaluate clamshell combination potency towards levels roosters. study employed 18 roosters un...

C19 steroids are converted to estrogens by aromatase P450 (P450arom). Aromatase expression in humans is regulated by use of tissue-specific promoters in the placenta (promoter I.1), adipose tissue (promoters I.4, I.3, and II), and gonads (promoter II). The use of each promoter gives rise to a population of P450arom messenger ribonucleic acid (mRNA) species with a unique untranslated 5'-terminus...

Substantial evidence supports the concept that estrogens cause breast cancer in animals and in women but the precise mechanism is unknown. The most commonly held theory is that estrogens stimulate proliferation of breast cells and thus statistically increase the chances for genetic mutations which could result in cancer. Another theory is that estrogen metabolism generates oxygen-free radicals ...

7or-(4'-Amino)phenylthio-l,4-androstadiene-3,17-dione(7a-APTADD), a potent enzyme-activated irreversible inhibitor, was examined in two different human cell culture lines, MCF-7 human mammary carcinoma cells and JAr choriocarcinoma cells. Both the MCF-7 and JAr cell culture systems exhibit aromatase activity, and 7a-APTADD was evaluated for its aromatase-inhibitory activity, for its ability to ...

As fish are ectothermic animals, water temperature can affect their basic biological processes such as larval development, growth and reproduction. Similar to reptiles, the incubation temperature during early phases of development is capable to modify sex ratios in a large number of fish species. This phenomenon, known as thermolabile sex determination (TSD) was first reported in Menidia menidi...

BACKGROUND The present study compares antiepileptic drugs and aromatase (CYP19) inhibitors for chemical and structural similarity. Human aromatase is well known as an important pharmacological target in anti-breast cancer therapy, but recent research demonstrates its role in epileptic seizures, as well. The current antiepileptic treatment methods cause severe side effects that endanger patient ...

INTRODUCTION Preeclampsia is a maternal hypertensive disorder with uncertain etiology and a leading cause of maternal and fetal mortality worldwide, causing nearly 40% of premature births delivered before 35 weeks of gestation. The first stage of preeclampsia is characterized by reduction of utero-placental blood flow which is reflected in high blood pressure and proteinuria during the second h...

This study was conducted to investigate the effect of women breast cancer on some hormones (Estrogen, Testosterone, prolactin) and biochemical parameters (Glucose, Cholesterol, Aromatase). The is done in Medical City Teaching Hospital Baghdad show age, body weight type feeding for with compared healthy women. Their age ranged between (24-70) years both groups. results showing high significant e...

Obesity is a risk factor for postmenopausal breast cancer and the majority of these cancers are estrogen dependent. Aromatase converts androgens into estrogens and its increased expression in breast adipose stromal cells (ASC) is a major driver of estrogen receptor–positive breast cancer. In particular, obesity-associated and tumor-derived factors, such as prostaglandin E2 (PGE2), have been sho...

The inhibitory effects of miconazole, an antimycotic agent, on aromatase activity for androstenedione in human placenta (105,000 X g pellet fraction) and ovary (800 X g supernatant fraction) were investigated. Various concentrations (0.1-100 microM) of miconazole, aminoglutethimide or delta 1-testololactone were added to the human placental preparation (1 mg protein) and then the mixture was in...
